Magellanic penguin herpesvirus 1 (MagHV1) was initially detected in 58.3 % of oiled Magellanic penguins (<em>Spheniscus magellanicus</em>) in South America presenting with respiratory distress characterized by a combination of necrohemorrhagic tracheitis, fibrinous air sacculitis, pneumonia, and death. Additional exploration is needed to understand how herpesviruses affect penguin health; however, there is currently a lack of rapid, sensitive, and specific methods for detecting and quantifying herpesvirus infections in this taxon. To address this problem, we developed a real-time quantitative PCR (qPCR) assay for the detection of MagHV1 in penguins. Using a commercial program, TaqMan-MGB primer-probes targeting the DNA polymerase gene were designed <em>in silico</em>. Inter- and intra-assay variability, dynamic range, limit of detection, and analytical specificity were assessed to validate the assay per MIQE guidelines. The resulting assay was highly specific for MagHV1, failing to amplify fifteen closely related avian herpesviruses. It performed with high efficiency (slope =-3.336, R<sup>2</sup> = 0.999, efficiency 99.40 %) and low inter- and intra-assay variability (coefficient of variation <u><</u> 1.67 % at all dilutions). Reaction efficiency was not impacted by the presence of penguin DNA from known-negative tracheal swabs. This qPCR assay has a linear range of detection from 10<sup>7</sup> to 10<sup>1</sup> viral copies per reaction and provides a valuable tool in the surveillance and characterization of MagHV1 epidemiology in penguins. This assay can further be used to detect asymptomatic birds and as an effective tool to monitor infectious individuals.</div></div>","PeriodicalId":17663,"journal":{"name":"Journal of virological methods","volume":"339 ","pages":"Article 115255"},"PeriodicalIF":1.6,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144933144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, inactivation treatments may affect the molecular structure of proteins in biological samples, and it is necessary to select an inactivation method that has the least impact on the target molecule associated with protein detection techniques. Cytometric Bead Array (CBA), a novel and powerful technology, allows the simultaneous quantification of up to 10–30 different soluble proteins from one sample, with a particular focus on various cytokines and chemokines in human body fluids. But only a few studies have investigated the effect of inactivation methods on relevant assays. Therefore, this study aims to investigate various viral inactivation methods and evaluate their impact on LEGENDplex™ bead-based immunoassays. By detecting eight plasma samples and eight ascites samples, we assessed the impacts of heat denaturation, γ-irradiation, and paraformaldehyde (PFA) inactivation methods on certain protein components in plasma and ascites by LEGENDplex™ bead-based immunoassays. The results showed that heat treatment and γ-irradiation treatment had little effect on LEGENDplex™ bead-based immunoassays in both blood and ascites, while PFA treatment resulted in changes in multiple cytokines and chemokines. Among twenty-six cytokines and chemokines, perforin, I-TAC (CXCL11), Eotaxin (CCL11), and MIP-3α (CCL20) were more vulnerable to heat denaturation, γ-irradiation, and PFA treatments. To sum up, our findings provide evidence to inform the selection of optimal inactivation methods for reliable cytokine profiling in SARS-CoV-2-infected samples.</div></div>","PeriodicalId":17663,"journal":{"name":"Journal of virological methods","volume":"339 ","pages":"Article 115244"},"PeriodicalIF":1.6,"publicationDate":"2025-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144895297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
